Abstract: Abstract of Disclosure A solid fuel conversion system feeds solid fuel to a burning area at a controlled and metered rate.  In the burning area, the solid fuel is dried before it reaches a burning bed of coals.  Once it reaches the bed of coals, it is advanced at a controlled rate from said drying means through the area of the burning bed of coals to an ash area. The fuel-drying and advancing is carried out by a series of grates having controlled amounts of grate movement.  The drying grate is set at a relatively steep angle (here, 60°) which breaks the free fall of an incoming curtain of solid fuel.  The fuel-advancing is accomplished by a series of grates which are set at less than a free-fall angle (here, 15°).  A reciprocating feeder moves the fuel-advancing grates back and forth by the controlled amounts.  The controlled rate of advance causes the solid fuel to gasify in the area over the burning bed.  An air delivery system controls the flow of gaseous fuel from the solid fuel burning area to a gaseous burning area.

Abstract: ABSTRACT            Title:                    CATCHES      A catch means as described which when fitted to co-operating parts of a piece of furniture enable those co-operating parts to be moved apart by a small amount after which, following manipulation of the catch means, may be more fully moved apart.    The catch means is said to comprise a stop element and a hooked element the two elements being mountable on the parts of the piece of furniture.  The hooked element comprises an elongate member having a first hook portion formed at one end thereof and at least one second hook portion formed along the length of it.  The first hook portion of each of the said at least one second hook portions extend in different directions from the axis of the elongate member.  The other end of the elongate members adapted for mounting on one of the parts of the piece of furniture in a number of different predetermined orientations enabling the stop means to engage one of the first and at least one second hook portions to prevent extended movement of the two parts by more than a prede-termined amount corresponding to the orientation in which the hook member is mounted.  In a preferred arrangement the hooked element is provided with two hooks facing in opposite directions.

Abstract: ABSTRACT Apparatus for preparing dies for a platen press comprises a lower bolster (1) and an upper bolster (3) between which a stack (120) can be in-serted on sliding rails (6) and (7).  The stack (120) is set under pressure by means of a hydraulic plate covered by a membrane (41), the rim-of which is guided by support-blades (43 to 46) and blade-guides (47 to 50).  The membrane (41) itself rests on a piston (52) acting on the stack (120).  This device allows the various dies to be used in a platen press for processing cardboard or paper, to be constructed outside the press, and therefore minimizes the down time of the press.

Abstract: ABSTRACT OF THE DISCLOSURE     Nonwoven wiper having improved absorbency characteristics and streak free wiping properties having a laminate construction including a relatively high basis weight middle layer of meltblown thermoplastic microfibers and, on either side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter.  These wipers are strong, fabric-like, and are useful for a wide variety of applications including industrial uses, food services, as well as many others.       The continuous filament layers provide strength and low lint properties while the combination exhibits improved wiping characteristics.  The laminate is preferably bonded by application of heat and pressure and the individual components are preferably treated with a surfactant.  The preferred combination of a layer of meltblown polypropylene microfibers having on either side a spunbonded polypropylene filament layer is particularly effective as an all purpose wiper.

Abstract: ABSTRACT    A form fill seal type wrapping machine uses equal speed conveyors which are start/stop controlled to accept randomly fed packages and uniformly spaced them for wrapping and sealing in a roll fed wrapping material such as thermoplastic film.          Different length packages can be wrapped without adjustment.          One embodiment uses a traveling transverse seal mechanism so the machine can run continuously.  Machine speed is enhanced by controlling dwell time for the transverse seal and time of travel for the transverse seal mechanism to be no longer than required to make the seal.  A fast return mechanism for the transverse seal mechanism operates at a speed independent of machine speed.

Abstract: ABSTRACT      Copper content in sulfide - containing materials such as ores or concentrates is extracted by leaching the material by means of a leaching solution containing iron (III) chloride and copper (II) chloride, the leaching process being regulated in order to keep the red-ox potential in the leach solution between 430 mV and 460 mV, whereby iron (III) chloride is reduced to iron (II) chloride while copper (II) chloride is kept in the bivalent state.  The copper content in the ore or concentrate is thereby leached as copper (II) chloride.  Copper (II) chloride is thereafter extracted from the pregnant leach solution by contacting the solution with an organic complex-ion forming extractant which extraction properties are dependent on the chloride concentration.
